Takashi Iwai e5ffa75afb ALSA: usb-audio: Validate MS endpoint descriptors
commit e84749a78dc82bc545f12ce009e3dbcc2c5a8a91 upstream.

snd_usbmidi_get_ms_info() may access beyond the border when a
malformed descriptor is passed.  This patch adds the sanity checks of
the given MS endpoint descriptors, and skips invalid ones.
